A stepping motor is provided to return terminals to initial states by fixing a support member to a bobbin and inserting the terminals into support grooves of the support member, thereby facilitating work. A stepping motor includes a bracket. A housing is coupled with the bracket. A stator has first and second bobbins(132,134), positive and negative terminals(133,135), coils(137), and tooth yokes(139). The first and second bobbins are installed at both sides inside the housing respectively, and one sides thereof are in contact with each other. One sides of the positive and negative terminals are formed in the first and second bobbins respectively, and the other sides thereof are exposed outside the housing to be electrically connected to a PCB(Printed Circuit Board) of a product. The coils are wound around outer peripheral surfaces of the first and second bobbins respectively, and lead lines(137a) thereof are connected to the positive and negative terminals of the first and second bobbins respectively. The tooth yokes are coupled with inner peripheral surfaces of the first and second bobbins. A lead screw is reversibly rotatable by supporting both ends thereof to the bracket and the housing respectively. A magnet as a rotor is fixed to an outer peripheral surface of the lead screw and reversibly rotates the lead screw through interaction with the stator. A support member(160) returns the positive and negative terminals of the first and second bobbins, which are bent by tension of the lead lines of the coils, to initial states.
